The fuel filter housing includes an outer surface with a connection interface for a fuel pump. This connection interface includes a fuel inlet port and mounting provisions for threaded fasteners. The fuel pump which completes the integrated assembly includes a fuel inlet and a fuel exit which is directly connected to the flow inlet of the housing. Further, the fuel pump is directly mounted to the outer surface of the housing in a unitized-type of arrangement. The upper endplate for the filter element is enlarged so as to extend beyond the outer diameter of the filter element and additional serve as a closing lid for the housing. A standpipe is mounted into the base of the housing and a knob, which is threadedly received by the upper end of the standpipe, provides the clamping mechanism for pressing the upper endplate tight against the upper end of the housing in order to complete the sealed interface.
